>I've never seen a sqlnet.log file that wasn't generated by a client process, and that's what the one you presented looks like. I see that it references an IP address and port 1287, while your listener seems to be configured for a server name (what IP does that resolve to?) and port 1521.
But we don't know what your problem is, you just said you have "the same" problem as someone else, but don't present any diagnostics. If the problem is that you can't start your listener, the first thing you need to do is show us the result of 'lsnrctl start', so we can see the exact error messages.
And keep in mind that the listener is a server side process. It runs only on the box that is actually hosting the database.
